AC Repair Services

We charge a $125 diagnostic fee for the time and travel it takes to evaluate your problem, determine what it’ll take to fix it, and quote a price for the recommended repair. If you approve us to complete the recommended AC repair at the time of the diagnostic, we’ll waive the $125 fee and only charge the AC repairs. We’ll complete the repair at the time of service unless your parts need to be ordered to finish the job. Once the part has been ordered and we have an estimated delivery date, we will schedule a date and time to go back out and repair your AC.

AC Installations

Getting a new AC system can be very costly and it’s one of the biggest home improvement projects you will do for your home, this is why AQS Mechanical offers financing with 0% interest for the first 18 months. AQS Mechanical, Inc is here to help you pick an AC suitable for your home and your wallet.  Most AC installation and replacement we perform includes a ten -year manufacturer’s warranty and one year labor warranty.

Sign up for a Preventative Maintenance Agreement

You wouldn’t drive your car for years without an oil change, so why would you not maintain your cooling system regularly? Many homeowners don’t maintain their AC units and expect their AC to function correctly. Unfortunately, you’ll end up paying more in repair costs than what you’ll spend on a tune-up or a preventive maintenance plan.

When you sign up for our preventive maintenance plan, you're ensuring your unit will work properly all year round. You’ll keep your energy costs under control and prevent premature AC replacements.
